tion, such as will enable others skilled in theart to which it appertains to make and use the sam e,reference being had to the accompanying drawings, and to letters of reference marked thereon, which form apartof this specification.

My invention relates to certain new and useful improvementsiu devices for securin g stovepipes in ,flues, and for combining therewith and attaching thereto a stove-pipe collar; and the invention consists in novel features of construction, combination, and arrangement of parts, all as will be hereinafter fully described, and set forth in the claims hereunto annexed.

Referring to the accompanying drawings, Figure 1 is a perspective View of my invention, showing my improvement ready to be inserted and applied to the flue. Fig. 2 is a side elevation of the flue-collar, showing in dotted lines where the collar and stove-pipe fastener are to be attached together. Fig. 3 is a vertical section through a chimney-flue, with my improvements as applied to the stovepipe for securing it in the flue.

In the drawings, A represents a metallic strap, wire, chain, or other suitable device, having one end secured to plate B at O, and which strap extends around the interior, its free end attached to lever F. The lever F is fulcrumed at its inner end to strap B, on the inside, at 0, while the other end of the lever projects a short distanoe'outside of the collar and bent end of strap B, by which it may be operated. Thislever is provided with a. pawl, P,adapted to engage theteeth E of the ratchetplate secured to the inner side of strap B, or made by turning up of the edge of apart of strap B, or otherwise making or attaching a ratchet. Thereby, where said lever is operated for adjusting the metallic strap A, it may be secured in any position desired, all as clearly shown in Figs. 1 and 2, and thus securely fasten the pipe to the open frame of straps H, G, and B. These straps extend from beyond I the inner wall of the fine to the outer wall thereof, and are bent at right angles at the end next to the strap A, as shown at 0 r, and are also provided with holes J I T, to permit of the insertion of rivets to secure the collar R thereto for holding it in position. ner ends of the straps B G H extendinto the chimney, beyond the inner edge of the wall,"to permit of each of them being bent outward, as shown at m n q, Fig. 1, to hold them firmly in the line. tached to the straps H B G at the outer bent ends, as shown in Fig. 1, 0 19 0", thus forming a complete collar and pipe fastener that is neat, compact, cheap, and efficicnt.

It willbe readily observed from the foregoing that the skeleton frame can readily be secured in the flue, the collar secured to the thimble, and the stove-pipe secured in place by contracting strap A and bringing a tension thereon, and held in any desired position by the lever, pawl, and ratchet. 1 (Shown in Fig. 1.)

I am aware of the patent of George Eckel, of Richmond, Indiana, for attachment for securingstovc-pipesin flue-thiinbles,No. 268,646, dated December 5, 1882, and that a thimble, strap, pawl, and ratchet are used therein. I therefore make no claim, broadly, to such devlces.

I am aware that a flue-hook having a bent shank, used in connection with a fastening band and collar for securing stove-pipes in fines, is old, and such I do not wish to be understood as claiming, broadly, as of my invention. In the patent of George Eckel before referred to, the metallic band only forms the means for securing the stove-pipe in the flue by contracting or expanding the band, while in the latter case above referred to the fluehook secures the stove-pipe in the flue, with a securing-band encircling it outside of the fine. In my invention a series of flue-hooks are connected to the adjustable baud shown in Eckels patent, which also assist said band in securing the pipe in the flue, and are adjusted with the band, and thereby form longitudinal bearings in connection with the circular bearing of the band as it is contracted or expanded, which bearing-surfaces of flue-hooks and band are all inside of the flue, and to the outer end of which flue-hooks the collar is connected.
